Is there a SaxParser that reads json and fires events so it looks like xml

Question

This would be great as it would allow my xml stuff to read json w/out any change except for the different sax parser.

Answer 1

If you meant, event-based parser then there are a couple of projects out there that do this:

1. http://code.google.com/p/json-simple/

   Stoppable SAX-like interface for streaming input of JSON text

   This project has moved to https://github.com/fangyidong/json-simple

2. http://jackson.codehaus.org/Tutorial

   Jackson Streaming API is similar to Stax API

   This project has moved to https://github.com/FasterXML/jackson-core

Answer 2

I think it is a bad idea to try treat JSON as if it was XML (which is what you are essentially asking); however, Jettison does just this. It exposes JSON content via Stax API (javax.xml.stream). And if you truly want SAX, writing wrapper from Stax to SAX is trivial as well (but not the other way around).

I also think you might get better answers if you explained bit more what you are trying to achieve, beyond mechanisms you are hoping to use. For example, there are many data binding tools for both XML and JSON; and using such tools could hide lower level details much better than using abstraction meant for one to process the other.
